Application filed November 17, 1913, Serial No. 801,322. Renewed January31, 1916.

To all whom it may concern:

Be it known that I, YSIDORO Rouo, a citizen of the United States ofMexico, residing at the city of Mexico, Mexico, have invented certainnew and useful Improvements in Car-Door-Locking Mechanism, of which thefollowing is a specification.

This invention relates to improvements in car door locking mechanism.

The primary object of this invention isto provide a locking devicespecially adapted for freight car doors and relates to that class ofsuch devices in which the locking means is associated with the hingemembers of the door.

Another object of the invention is to provide a hinge lock adaptable forefficient use with a door that is slidably mounted although beingcapable of use ing door structure.

With these general objects in view and others that will appear as thenature of the invention is better understood, the same consists of thenovel combination and arrangement of parts hereinafter fully described,illustrated in the accompanying drawings, and pointed out in theappended claims.

In the drawings forming a part of this application and in which likereference characters denote corresponding parts throughout the severalviews: Figure 1 is a front elevation of the mechanism controlling theopening and closing of the car door and the actuating of the registerand indicator, 2. portion of the door being shown and said mechanismillustrated and detached from the car. Fig. 2 is a top plan view of theswinging hinge device at the lower end of the door and showing theposition of the elements at the first stage of the door openingoperation. Fig. 3 is a vertical detail of a portion of the door showinga channel guide support and pin and bottom plate upon which the doorslides.

Referring more in detail to the drawings, it will be noted that the cardoor 1 may be broadly stated as slidably positioned upon the side of thecar 1 with the bottom portion of the door slidable upon a guide plate 8having a marginal inclosing flange 8 curved as at 9 at the forward endof the door to give proper direction to the door during both the openingand closing operation.

Stationary plates 2 and 2 are secured to the frame of the car adjacentthe rear edge 1 of the door when closed, at the top and Specification ofLetters Patent.

secured longitudinally inclosing both the top and the bottom of thedoor, said plates provided with longitudinal slots 7 which receiveheaded pins 4 mounted upon the hinge plates 3, 3* and by which means thedoor is capable of hinging outwardly as shown in Fig. 3 and slidinglongitudinally upon said pins 4 to the open position shown indotted-lines in Fig.2.

Upper and lower bolts 16and 16 respectively are shdably mounted in strapplates 16*" and 16 respectively to be moved by the actuating mechanism23 away from and toward each other. The opposite free ends of said bolts16, 16 are projectable within and through openings 16 and 16 of the saidhinge plates 8, 3 when the said openings of the plates are brought intoalinentlent with the said bolts. The stationary plates 2, 2 are providedwith keeper openings 16, 16", and into which said ends of the bolts 16,16 are respectively adapted to enter when the said ends and the saidopenings of the hinge plates are brought into registry therewith and allof which is occasioned only upon the complete closing of the door 1.Levers 25, 24 have their free ends hinged to said bolts 16, 16 by therivets 25 and 24 respectively, while said lever 24 has its opposite endpivoted at an intermediate angular point 26 to said plate and has anangular end extension 25 engaging within a curved portion of the lever24. A spring 28 secured to the plate 23 bears upon the lever 24 normallyretaining the same and its bolt 16 depressed while a similar spring 29engages the lever 25 with an upward pressure for normally holding thebolt 16 upwardly.

From the above detailed description of the device the complete operationthereof will be apparent as the manner of locking and unlocking the doorin conection with the hinge members upon which the dooris mounted isevident.

What I claim as new and desire to secure by Letters Patent is 1. Adevice of the class described comprising in combination with a car door,stationary oppositely positioned keeper plates, journaled hinge platesflatly engaging said keeper plates, said journaled plates and keeperplates each provided with perforations therethrough, locking bolts withtheir ends projectable through the perforations of said journaled platesand adapted for entering the perforations of said keeper plates upon analinement of the perforations of said journaled and keeper plates.

2. A locking mechanism comprising in combination with a door, stationaryoppositely positioned keeper plates having keeper sockets in their innerfaces, longitudinally slidable locking bolts mounted between the saidplates and in alinement with the said sockets, journaled shiftable hingeplates for the door flatly engaging the inner faces of said keeperplates and positioned between the said keeper plates and the free endsof said bolts when the said bolts are retracted in their unlockedpositions, the said hinge plates having perforations therethrough p0-sitionable in alinement with the said bolts and keeper sockets when thedoor is in its closed position.

3. A locking mechanism comprising in combination wlth a door, oppositelypositioned keeper plates having parallel inner sockets when the door isin its closed posi- 7 tion and annular holding shoulders for the saidhinge plates provided upon said rod adjacent the said hinge plates.

In testimony whereof I hereunto afiix my signature in presence of twowitnesses.
